,To :all '107mm it may concern. y

fornia, have invented new and usetul AIniprovenients in Electrical lVaterHeate-rs, of which the following-1s a specification.

My invention relates to improvements in `.electrical water heaters and particularly in connection wherebythe ilow vot water will be instituted through the heat-ing mechamism, or out off therefrom in such relation that the heating elements will be amply pro.- tected by water before and during the ,time while the electrical current is flowing.

It consists in the combination ot' parts and details of construction,y whiclrwill be more fully explained by reference to the accompanying drawings, in which the figure is a partial section land elevation of my appa ra-tus.

ing a current.- of flowing water, and to insure the heating mechanism being always protected hy' a body of water while the electrical current is flowing.

In carrying out my invention I forni a' casing which may be made of ordinary tubing, having suitable closures at the end and an intermediate diaphragm '2, which serves to separate the water heating space and'meehanism, from the switch'mechanism.

@The water heating portion consists of aseries'of coils of wire' 3, which may be of naked wire with the coils so separated thatl the electrical current will he4 forced to pass through 'the length of the coil and not ne short c nited. ranged in any suitable or desired manner, as indicated, c1nd connection is made hetween the t which an electrical current may he trans mitted to en the coils. As these coils are made w h a certain resistance to tine passage' of tt `amount cf heat will be developed in them 'to lheat, the water which may be passed through the coil containing chamber.

In thepresent'ca se I have shown the casing A. having an inlet passage at 4l on one side near the top and a ldischarge'passage through the bottom, as at 5. In order to.

'connect the device with the sour@ 0f SUPPlIf? .I have shown a short right and lett threaded .tn he, G, one end ofwhich screws into the end of the nipple, et, upon the casing, A, and the other may he simultaneously screwed into the nipple 7 of a faucet 8 of any suitable or desired description.

In the present case I have shown what is termed a Fuller 7 cock vhav-ing an operat-- ing lever or handle 9 and the standard l0 of such a cock is'here shown as fixed to one side ofa wash hasin 11;l this being the nor-- mal position ot such water cocks. It will then be seen that by connecting vthe nipples and 7 by the short piece of tubing 6, the naratus will be'cenveniently located with is, tion to the basin, In order to open the watersupply and to close the .electrical circuit simultaneously, I have shown an eXtension .l2 ot' the handle 9 and a` heart-shaped lever i8 tulcrumed to a standard I4 on the casing and having its divergent ends l adapted to contact with push buttons 16 of that class of switch known as the double pole flush switch V .The remaining upis connected with the arm .l2 hy means of a connecting rod or link i8 which is curved into a segmental are, as shown, so as to most effectively Vtransmit the movement of .the lever to the switch actuating member. The

These coils may he ar! and the switch through te electrical clxrrent., a sntlicientarm 18 may be perforated with holes, as at 1li), so that the end of the' connecting arm 12 may he adjusted to any of the holes and thus lengthen-or shorten the lever 18, so as to vary the opening and closing of the Water supply and the switch. v

It will be manifest that in order to pro tect the apparatus from injury, it will al ways he necessaryto have cody el water `flowing through heating chamber while the electric current is flowing, and this posi.- tion of the connect-ing linie such thaty the waterwill commence 'to flow an instant bek tore the electrical circuit is closed and will continue to flow an instant after the parts `are moved to close the electrical switch. The arm lis also so disp ed that, it desired, the vater cool; will be opened shortly before the electrical circuit is closed and thus a supply of cold water may he passed through the apparatus, if desired.r By this construction I am enabled to provide a very. economical and effective heating deviciia'and to so reduce the mechanism intern wardly extending angle 17 -o' the part 13 i mediate ofthe Water cock and the electrical switch that it will be. cheapand little liable to get out of order.

Having thus described my` invention,vvhat I claim and desire to secure' by Letters 'Patent isf'- 1. Thecombination :with 'a'cock having. a'n actuating lever,`a casing, and an electrical heatin locate in the casing having .push but-tons extending :through the top, ariangular le ver fulcrumed between the buttons with two `of itsanglesadapted to cont-act with and coil, of a double pole flush switchl actuating lever, a casing, and an electrical ,heating coil, of a ldouble. pole flush switch located in Ithe casing having push buttons 'extending through the top, a triangular lever fulcrumed between the buttons with twoof its angles adapted to contact with and alternately `depress the'buttons, a curved vlink having one end pivoted t0 the third I angle-of the' lever, .an extension of the cock y actuating lever' with which the Iother end of the link is connected, and means to vary the length of the connecting link.
